Radon Mitigation in the Twin Cities Metro
The Twin Cities metro holds more than half of Minnesota's housing, and radon treats all of it the same way. Hennepin and Ramsey counties are both rated Zone 1 on the EPA Map of Radon Zones, the category with the highest predicted indoor levels, and the Minnesota Department of Health reports that 2 in 5 homes tested statewide pose a significant health risk.
From a 1910 Minneapolis bungalow to a 2020 exurban build with a passive pipe already in the attic, the fix is the same trade: an independent contractor licensed by MDH, a free written quote, and a verified result. We connect metro homeowners with those contractors in Minneapolis, St. Paul, Bloomington, and the surrounding suburbs.
The Metro Radon Picture
Both core metro counties carry the EPA's highest radon potential rating, and MDH treats mitigation cost as a real barrier: it does not fund the work itself, but it lists home-repair loan and grant programs from other agencies that may be offered to homeowners who qualify, an acknowledgment that plenty of high-radon metro homes remain unmitigated. Testing is cheap in the metro, where county and city health agencies often sell low-cost kits, so the gap is awareness, not access.

The metro sits on a thick blanket of glacial deposits, the till and outwash left by the ice sheets that shaped Minnesota, resting over sedimentary bedrock. MDH attributes Minnesota's radon problem to the uranium that decays naturally in these rocks and soils, and to a heating season that pulls soil gas indoors for months at a time. That combination does not respect city limits, which is why readings vary more house to house than suburb to suburb.

The metro spans every foundation era Minnesota has: stone and limestone basements in the pre-war cores, concrete block under the postwar ramblers, poured walls in the later suburbs, and passive radon rough-ins in everything permitted after June 1, 2009 under Minnesota Rules 1303.2400. Licensed contractors work across all of them daily; the era mostly changes where the suction point goes and how the pipe routes, not whether the system works.

Verify Your Contractor's Minnesota Radon License
Before you hire anyone for radon work in Twin Cities Metro, check their license. The Minnesota Radon Licensing Act, Minnesota Statutes section 144.4961, requires anyone who performs radon testing, mitigation, or laboratory analysis for compensation to be licensed by the Minnesota Department of Health, and every mitigation system installed under the law must carry a numbered MDH system tag. On a paid install, a missing tag is the fastest red flag a homeowner can check. A licensed professional expects the question. Three things to ask before you sign:
- Can I see your current MDH radon license, and is the company licensed too?
- Will the installed system carry the MDH system tag required under the licensing law?
- Will I get a written, itemized estimate and a follow-up radon test that confirms the system works?
Twin Cities Metro Radon Questions
Is radon really a problem in the Twin Cities metro?
Yes. Hennepin and Ramsey counties are rated Zone 1, the EPA's highest radon potential category, and the Minnesota Department of Health reports 2 in 5 tested homes statewide pose a significant health risk. Metro homes are not exempt; MDH data shows plenty of high results across the core cities and suburbs alike.
Which Twin Cities homes are most likely to go unmitigated?
A 2020 MDH analysis found metro mitigation rates track neighborhood income and home values: lower-value and rental housing is less likely to be tested and fixed even where radon potential is identical. If you rent or bought an entry-level home, testing is the step most often skipped.
Do metro condos and apartments need radon testing?
Ground-contact units matter most. Radon enters from the soil, so basement and ground-floor units carry the exposure risk, while upper floors typically test lower. MDH recommends testing the lowest lived-in level; in multifamily buildings, testing and mitigation are jobs for licensed professionals working with the association or owner.
What it costs, and what happens after you send it
- What does radon mitigation cost in Twin Cities Metro?
- the Minnesota Department of Health puts a mitigation system at $1,500 to $3,000 installed. For context, the EPA reports a national average of about $1,200 nationally, with a typical range of roughly $500 to $2,500. Foundation type, home size, the run of the pipe and the fan required all move a real quote inside or past that band. A licensed install also carries $75, the MDH system tag that a licensed installer applies, which MDH cautions is missing on jobs priced below the range. The Minnesota cost guide explains what moves a quote, with every figure cited.
- How fast will someone get back to me?
- Calls and form submissions reach Compass Camper LLC directly. We read the request and pass it to an MDH-licensed radon professional, usually within about an hour during the day. That professional then contacts you to look at the home and quote the work on their own schedule.
- What work is covered?
- Radon mitigation, radon testing, real estate radon testing, and new construction radon systems. See every service.
Only the MDH-licensed professional you are matched with can price your actual home. Compass Camper LLC does not test or mitigate radon and does not quote it.
